Everybody loves the drag and drop nature of OS X. Drag an app into your applications folder, and it’s installed. You’d think it would be that easy to delete an app — just a matter of dragging it to the trash. But it’s not. Applications install preferences, caches, and other support files throughout your computer that take up space and generate clutter. Deleting these by hand every time you delete an app is a pain.

This is from the official site of AppZapper. A program for OS X that has been a true friend to me. So with no further adieu, I present to you; AppZapper!
